RAW'-WATER SYSTEM `FOR MAKING ICE.

`implication ,led September 26, 1922. Serial No. 590,585.

My invention relates to devices for air agitation oi' raw Water Within ice cans when makingl artificial ice, and more particularly relatesto mea-ns l'or controlling` an auto matic valve in the air supply.

The purposefotmy invention is to provide a quick` and easytlexiblevconnection from an air lateral to the Vair distributing pipe Within an ice can7 using an ordinary pipe or pipe litting to open an automatic valve and to keep it open While the connection is made.

A further purpose is to cheapen andsim` plit'y the device by yusingl anordinary pipe end as the valve-operatinginea-ns. y l further purpose is to provide a valveoperatingl couple Within a-:tlez-:ible connection by which an air pipe may be suspended or otherwise connected from a lateral or a feeder for several such pipes may be so connected to any air supply pipe Without requiring` centering ol:l the pipe or feeder with respect to the opening in the lateral.

Further purposes will appear in the specilication and in the claims.

I have preferred to illustrate-lily invenn tion by but one general' form, showing tivo applications ot it which have proved to be simple, eiiective and inexpensive and Which at the same time .Well illustrate the principles ot my invention. s

Figure l is a broken sectional elevation illustrating one application of my invention, the valve being` in closed position.

Figure 2 is a section through the line 2?-2 of Figure l.. Figure 3 is a broken sectional elevation similar to Figure l but showing,` the end oi' the supply pipe holding the. valve open.

Figure l is a brolren sectionalelevation to reduced scale illustrating connections tor the supply of air to several cans upon thesame Figure 5 is a `broken and elevation, to larger scale than Figure Ll, illustratingl connections to 'supply cans upon both sides oft the lateral.

In the drawing-s like numbers refer to like `parte in all. ligures.

Describing in illustration and not in limitation and 'rellerring` to the drawings z-fl In making,v artificial ice in cans, raW Water in canslsurreunded by cold brine, is tatedby air trom depending air-tubes 16 until ice closes thetube outlets and the tubes freeze in.V The tubes are preferably placed partly sectional y substantially coaxial with the cans so as to remainopen as long as possible, the Water along the can axisbeing last to freeze.

ritter the tubes are frozen in they are disconnected'and a thawing needle applied to remove the pipe. I connect and disconnect at a point Where the combined structure secures otherV advantages, by nipples 1? in hose connections 18 `from the air-supply pipe i9. This supply pipe is connected by flexible hose connection 20 andthe nipple 2l. with thevair lateral 22, controlled by anv automatic valve 23, which closes in the direction oliair travel. i

So far as I am aware all previous valve connections have been complicated by requiring a specially prepared terminal `upon the distributing` pipefwhich is connected with the lateral, Whereas I adapt the valve to automatic opening,` on connection `with any pipe (under which term I aim to include also the tubular ends ot Ts or other littings) both to reduce the expense andto facilitate substitution ol other connecting parts.l Y

1 The nip'plefl. isthreaded tit/24; so that it may bescreyv'e'd'into the lateral and carries a valve seat 25 at its threadedV end. ln intermediate polygonal Wrench hold 26 .is provided and the shankV 27 is litted to receive llexible hose connection 20, conveniently clamped to it by clamp 28. The valve disc 23 is carried coaxial with the nipple 21 and valve seat 25 upon a stein 29 Within and through the nipple. The stem member has non-circular and preferably substantially square portions 30 and 31 loosely fitting the interior oi' the nipple near each end and serving to maintain the stem and valve coaxial with the nipple While per mitting` the air to pass the stem.

The disc 23 lits over a threaded end 32 of the stem and is held in place against the shoulder 33 by nut 3l.

The pin 35 passes through the end ot the stem and limits the opening` ot the valve by stop engagementwith the end 36 oi' the nipple, the stop pin being so placed as to limit the maximum air delivery to that merely adequate for proper service. i

The transverse air supply pipej19 is pret erably tapered slightly at the extreme end, 37 to lit Within thehose connection Q0 and when in place for air supply to the air-tubes 16 engages the pin 35 to open the valve and to maintain it open as long` as connection is made. The movement ot the pinis stopped by the end of the nipple, as best seen in Figure 3. It will be noted that the end of the pipe need not be specially prepared nor turned in any special position, that the size of the pipe may be varied Within the range of gripping connection with the hose coupling and that no exact alignment of axis or direction of the pipe is required.

W'hen the air-supply pipe is disconnected so that the cans may be lifted out, the valve is free to close', and does so by reason of the ygreater' pressure within the lateral as compared to the pressure on the discharge side of the valve.

' Figures 4t and 5 show respectively different ways of placing the air-supply pipe with respect to the air lateral.

' In Figure 4 the flexibility of the connection not only frees from necessity for matching up the axis and direction of the air tube with the nipple but permits the air tube to `hang freely in a vertical position even if the nipple be slightly misplaced in direction or position. A ferrule is shown between pipe 16 and the hose but connection can be made direct between pipe and hose.

In Figure 5 the air-supplypipe supplies air tubes on both sides of the lateral and in order that it may lift away when disconnected from the air tubes is placed above the lateral, the connection into the lateral being on the top instead of the side, as shown in Figure 4t. Corresponding members of Figures 4 and 5 are given the same numerals and the description applies to both. A ferrule canlbe used between the tube 19 and Vthe air pipe in" Figure 5 similar to the ferrulein Figure 4. y

In view of my invention and disclosure modifications and variations will doubtless become evident to others skilled in the art and it is my'wish toinclude herein all such as fall `within the reasonable spirit and scope of my claims.
